I had same issues with both my sig and avatar, hence why i ended up using a ready-made gif for my avatar and no signature. I tried many times in Photoshop and i got exactly the same problem as message and problem as Cozz

Bump. And yeah, i'm trying to upload this new "Kramer" siggy that I made in CS3. It's 87.7kb and it's too big. No matter how I compress it, it only gets to 30kb... apparently the rules say it can be 100kb but I cant seem to be able to upload anything =(
